Abstract: High Resolution Image Download MS PowerPoint Slide Borophene oxide (BO) was synthesized using a modified Hummer method and added at different ratios into a plasticized polylactic acid/polyethylene glycol (PLA/PEG) matrix via a solution-casting technique. Characterization of the produced films for potential packaging applications was carried out through thermal, mechanical, structural, morphological, and antibacterial tests. The addition of 0.5 wt % BO to the plasticized PLA film resulted in an approximately 72% increase in the tensile strength (22.6 MPa). Increasing the BO content decreased the elongation values. In TGA analysis, the Td 10 temperature of the PLA/PEG matrix increased from 310 °C to approximately 338 °C with the addition of a low amount of BO. The water vapor barrier of the plasticized PLA films was enhanced with 0.5–0.7 wt % BO addition but diminished at higher BO concentrations. The resulting films exhibited greater antibacterial activity against S. aureus than E. coli . Considering all film properties, the developed films were shown to be promising for biomedical and especially packaging applications, where the vapor permeation barrier and Gram-positive bacterial contamination are critical concerns due to the BO content.
